 1 GB with an overview of T2 copper 
 Purple with copper because of its name. It may not be pure copper, and sometimes a small amount of oxygen elements or other elements to improve the material and performance 
 And, therefore, classified as copper alloy. Chinese copper processing material with a composition can be divided according to: normal copper belt (T1, T2, T3, T4), oxygen-free copper (TU1, TU2, and high-purity, vacuum oxygen-free copper), deoxidized copper (TUP, TUMn), add a small amount of special copper alloy elements (arsenic copper, tellurium copper, silver, bronze) four. Copper with electrical and thermal conductivity second only to silver, widely used to produce electric and thermal conductivity equipment. Copper belt in the atmosphere, water and certain non-oxidizing acids (hydrochloric acid, sulfuric acid), alkali, salt solution and various organic acids (acetic acid, citric acid) has a good corrosion resistance, for the chemical industry. T2 copper belt contains fewer impurities, slightly higher than T1. The purity up to 99.90%. Copper commonly used in industry for the T2 copper belt, cheap, affordable. 

 (2) the name of imported materials with copper C1100 
 C1100 Copper with Copper II, also known as industrial metal copper, more than 99.5% purity, purple, also known as pure copper. It has excellent electrical conductivity, thermal conductivity, corrosion resistance and weldability, the conductivity at room temperature, second only to silver. Processing copper belt, which was divided into four kinds of grades, that I, II, III and IV with copper, purity of 99.95%, 99.90%, 99.70% and 99.5%; the so-called T1, T2, T3, T4. 

 3 GB with the characteristics of T2 copper 
 Good electrical conductivity, thermal conductivity, corrosion resistance and workability, welding and brazing. With lower conductivity, thermal conductivity less impurities, small amounts of oxygen on the electrical conductivity, thermal and processing properties have little effect, but could easily cause a "hydrogen disease", not at high temperature (eg> 370 ℃) reducing atmosphere processing (annealing, welding, etc.) and use. Often contain oxygen, sulfur, lead, arsenic, bismuth, phosphorus and other impurities. Has excellent electrical conductivity, thermal conductivity, moderate mechanical properties. Can be used for the preparation of copper alloy and alloy elements. Electric fields are widely used for electrical conductivity, thermal conductivity material. With the reverberatory furnace and other pyrometallurgical copper, refined copper electrolysis. Preparation or sources: natural copper are important chalcopyrite, chalcocite, cuprite and malachite, but are low grade. Sulfide ores can be calcined to a small amount of sulfur dioxide and coke after crude copper eutectic, and then reduced to blister copper, and finally refining electrolysis derived. Copper with trace impurities on the conductivity of copper, thermal conductivity have a significant effect. Including titanium, phosphorus, iron, silicon significantly lower conductivity, and cadmium, and zinc is little effect. Oxygen, sulfur, selenium, tellurium, etc. in the solid solubility of copper in small, brittle compounds can be generated with copper, has little effect on the conductivity, but can reduce the processing of plastic. Ordinary copper with hydrogen or carbon monoxide in a reducing atmosphere in the heating, hydrogen or carbon monoxide is easy and cuprous oxide grain boundaries (Cu2O) effect, resulting in high pressure steam or carbon dioxide gas, copper can break. This phenomenon is often called copper the "hydrogen disease." Oxygen on the copper welding and harmful. Bismuth or lead and copper to generate low melting point eutectic, thermal embrittlement of copper; and brittle thin film of bismuth was distributed at the grain boundaries, but also to produce copper cold crisp. Phosphorus can significantly reduce the conductivity of copper, but copper can increase the fluid flow, improve weldability. Amount of lead, tellurium, sulfur, etc. can improve machinability. 
 Light weight, good thermal conductivity, high temperature strength. Commonly used in the manufacture of heat transfer equipment (such as condensers, etc.). Oxygen equipment is also used for low temperature piping assembly. Small diameter copper tubes used for conveying pressure of the liquid (such as lubrication systems, hydraulic systems, etc.) and used as instruments of piezometer tubes. 
 Brass with sturdy, corrosion-resistant properties, and become a modern residential housing contractor in all the water pipes, heating, cooling pipe installation preferred. 
 1, copper is the economy. Because copper is easy to process and connect to the installation, you can save materials and total cost, stability can be reliability, eliminating the need for maintenance. 
 2, copper is lightweight. The twisted threads of the same diameter pipe, the brass does not require a black metal thickness. When installed, the delivery cost of copper is smaller, easier to maintain, take up less space. 
 3, the shape of copper can be changed. Because copper tube can be bent, deformed, it can often be made and elbow joints, smooth copper tube bending to any angle to allow bending. 
 4, the copper is easy to connect. 
 5, copper is safe. No leakage, no combustion, no toxic fumes and corrosion.
